Iyo, a rabbit-like inhabitant of the alternate world AniYoko, thrives as the self-centered yet undeniably charming member of the Happy AniYoko Trio. Her cheerful exterior masks a flair for drama and vanity, often prioritizing personal comfort over others’ needs. Interactions with Kenta swing between mischievous teasing and outright clashes, though rare gestures—like slipping his favorite meat into shared meals—hint at buried kindness.

Her arsenal includes the Iyo-pe Beam, a shockwave unleashed when irritated; the Iyo-chander Attack, swift kicks or shoves to assert dominance; and the Super Iyo-pe Bomb, a leaping strike to flatten foes. Her versatile ears double as storage, housing Special Diet Juice, a miniature furnished room for her pet turtle Mr. Nonoko-chan, and even slicing carrots like blades.

When ignored or slighted, she theatrically “dies,” reviving only upon receiving heartfelt apologies—a testament to her fragile ego. Born January 4 (Capricorn), she claims three years of age but once impersonated a sixteen-year-old. Her wide, black-lined eyes occasionally flicker with crimson square pupils, adding to her eccentric charm.

She needles Ami with relentless playfulness, refusing exclusion, and torments Issa with ghost stories. Her bond with Kenta thrives on bickering and scuffles, yet flickers of mutual care pierce the chaos. While her vanity sparks friction, she remains pivotal to the trio’s balance, weaving camaraderie through mischief. Relationships beyond the trio, including with AniYoko’s horse-like leader Yamanami, remain sparse, her focus anchored to her immediate circle. No deeper backstory or evolution defines her—her static, vibrant persona drives her role, unchanged across tales.
